The later cars transfer allows this.

Also, I am reading I had the earlier ratio incorrect. Still fixed, but fixed at 38/62.

The video shows an X5 with ZERO grip on all wheels. The later portion of the video shows that the other wheels are spinning at the same rate or close to it until the braking kicks in. This happened quite a bit on my '04 3.0 in the snow and would be expected in that case.
